Jalen Beeks

The Red Sox have officially struck a deal to land righty Nathan Eovaldi from the Rays, as Ken Rosenthal of The Athletic first reported (via Twitter). Young lefty Jalen Beeks will go to Tampa Bay in return, per Marc Topkin of the Tampa Bay Times (Twitter link).

This swap is the second in the last two days that sends rental pitchers between AL East rivals. Yesterday, of course, the Yankees got lefty reliever Zach Britton from the Orioles. The Yanks will temporarily dodge Eovaldi, who had been scheduled to start against them today, but will surely see him down the stretch.

For Boston, the move will add an intriguing arm to their roster. Eovaldi has worked as a starter almost exclusively in his career, and may well continue to do so over the final two months of the season as he helps to shore up a Red Sox rotation that is showing a few cracks. But his role in the postseason could end up being an interesting one. The Sox have an unusual number of southpaws among their rotation candidates, making Eovaldi an interesting pitcher to pair up with one or more lefties.

Eovaldi is a pure rental, and a cheap one at that. He’s earning just $2MM this year, with some affordable incentive pay also included. Though it took him quite a while to make it all the way back from Tommy John surgery, Eovaldi has returned with vigor thus far in 2018.

Over 57 frames in ten starts this year Eovaldi has pumped his customary 97+ mph heat while working to a solid 4.26 ERA. But that only tells part of the story. He’s sporting a career-best 20.1% K%-BB% while generating more swings and misses (11.0%) than ever before, though he has also been touched for 11 long balls. Eovaldi merited rather lofty placement on MLBTR’s latest ranking of the top trade deadline candidates and has certainly increased his stock heading into free agency.

It seems likely the Rays will have designs on using Beeks in a flexible manner, too, but on a more regular basis. The 25-year-old has been roughed up in two MLB outings this year, but has also turned in increasingly interesting results in the upper minors in recent seasons.

Over 16 Triple-A starts in 2018, Beeks carries a 2.89 ERA with 12.1 K/9 and 2.6 BB/9 over 87 1/3 innings. That strong showing led Baseball America to rank Beeks the Sox’ sixth-best prospect in its most recent look at a thin Boston farm. While he’s considered likely to be a back-end rotation piece in the majors, he possesses an interesting four-pitch mix and seems a good fit for the Rays’ counter-culture approach to building a pitching staff.

The Red Sox announced Friday that they’ve selected the contract of right-hander Justin Haley from Triple-A Pawtucket and optioned lefty Jalen Beeks back to Pawtucket in his place. Boston’s 40-man roster is now up to 39 players.

While this will mark the Red Sox debut for Haley, whom the club selected in the sixth round of the 2012 draft, it won’t be his MLB debut. Haley was selected by the Twins in the 2016 Rule 5 Draft and broke camp in Minnesota last year, but he was ultimately designated for assignment and returned to the Sox after posting a 6.00 ERA over 18 innings as a seldom-used long reliever.

Things have gone much better for the now-26-year-old Haley in Triple-A, where he owns a career 3.28 ERA with 7.3 K/9 against 2.3 BB/9 in 203 1/3 innings. That production is right in line with his marks so far in 2018: a 3.18 ERA, 8.3 K/9, 2.5 BB/9 and a 44 percent ground-ball rate in 56 2/3 innings out of the Pawtucket rotation.

The 24-year-old Beeks, meanwhile, will head back to Triple-A for continued development. He was called upon to make a spot start last night against the Tigers and was ambushed for five runs in his first Major League inning, though he settled down and allowed just one run over the next three innings. While it wasn’t a great debut, Beeks should still have ample opportunity to factor into Boston’s long-term plans. The former 12th-rounder owns a 3.38 ERA with 10.5 K/9 against 2.8 BB/9 in 152 Triple-A innings.

As detailed earlier this morning at MLBTR, the deadline for Major League clubs to add players to the 40-man roster in order to protect them from next month’s Rule 5 Draft is tonight. Because of that, there will be literally dozens of moves between now and 8pm ET as teams make final determinations on who to protect and who to risk losing in next month’s Rule 5 draft. This process will lead to smaller-scale trades, waiver claims and DFAs, but for some clubs the only necessary moves will simply be to select the contracts of the prospects they wish to place on the 40-man roster. We’ll track those such moves in this post…

The Nationals announced that they’ve selected the contracts of third baseman Kelvin Gutierrez and right-hander Jefry Rodriguez, thus adding both to the 40-man roster. MLB.com ranked Gutierrez 12th among Nationals farmhands. The Nats still have three open spots on their 40-man roster, so they could make further additions by adding players from outside the organization between now and the deadline. They could also simply save those spots for future trade or free-agent acquisitions.

Note: Players that signed at 18 years of age or younger and have played five seasons of pro ball are Rule 5 eligible unless added to the 40-man roster today. Players that signed at 19 or older and have played four seasons are also eligible if they’re not added to the 40-man roster today. (In other words, college draftees out of the 2014 class, high school draftees out of the 2013 class and most international amateurs signed in the 2013-14 international period are eligible this year if not protected.)
